1. First off, how do I make my path to my database relative? The path is currently absolute and is: Data Source=J:/College/AS_DSFinalDatabase1.accdb
2. Second of all, where do I save my database in the project? I want it to be included in like project folders...kind of like the App_Data folder in ASP.Net.
3. I'm recieving an error whenever I try to populate more than 1 DataGridView upon form load for some reason...I've tried 5 different ways of writing the code, and I get the same error...there's no error description, so does anyone know what the issue is? Here's the error:
I'm using a OleDB connection to a access database. I'm entering a row into the database to set some user preferences. What i need to get is get back the row ID of the row I just entered. I'm more familiar with PHP and with PHP I use use this entry

What is the code to connect to data base executing the query and displaying the result in a textbox.
View 1 RepliesI wonder is there another way to connect,edit access database with out using OLEDB command.I want to insert,delete data from access table without using oledb.
View 3 RepliesJust wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

View 1 RepliesI've recently made another question about connecting to MS-ACCESS database with .NET in C# or VB.NET. It worked just as intended with MDB, but with accdb it caused an exception in
conn.Open();which follows:
Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.
If (Tech_TextBox.Text <> "9999") Then
If File.Exists(ExportFolder + "" + Tech_TextBox.Text + ".pdf") Then
txtRouted.Text = txtRouted.Text + vbLf + Tech_TextBox.Text
myFileName = (ExportFolder + "" + Tech_TextBox.Text + ".pdf")
If cbPDFPrint.Checked Then

I have created an auto emailer to distribute our work routes for my colleagues. Problem is I made it easy for the management team to update the list. List is ordered by Tech Number, First name, Last name, Email address.
I have coded this in VB.NET 2008 using Database sources and drag-n-drop the table on the form. I let VB do most of the coding of the connection and text boxes. (IE If (Tech_TextBox.Text <> "9999") Then)What I would like to do, instead of using a bogus tech number as an exit. I need an 'IF Then" or 'DO UNTIL' after last record.
I am inserting data from vb.net to oracle but I am unable to insert datetime except date into oracle. I want to insert date and also time of entry into database:
cmd.Parameters.Add(":STARTING_DATE", (OleDb.OleDbType.[Date].))
cmd.Parameters(":STARTING_DATE").Value = DateTime.Now()
cmd.Parameters(":STARTING_DATE").Value = txtStartDate.Text

I'm using Visual Basic Express 2008 (VB.NEt). I've created a project which
connects to a Microsoft Access Database (OLEDB) & displays the records using textboxes in the windows app.
I need to add a button which exports the database to a fixed length text file. Does anyone know the code I would use to do this?
I've got a problem whereby I get Permission Denied while accessing a database via OleDB. I know how to unlock this but i'm not permitted to do so. I was wondering if ODBC would work? I'm not sure on the settings around this on my the PC where I'm going to use this application but wonder if this has less security around it. your thoughts until I can test this next week. Or is there another way you may know that I can use a database. (access)

View 5 RepliesI am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?
I have been trying my hand at this for some days now and just cant get anything to work.

Dim con As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=Customers.mdb"
Dim cnn As New OleDb.OleDbConnection(con)
cnn.Open()

View 2 RepliesThe program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters."
